Systems Science and Systems Engineering 2003年第3期12卷 360-371页

作者： Ju-liang ZHANG jian chenDepartment of management Science and Engineeringschool of economics and management tsinghua university, beijing 100084, china. tsinghua university Department of Management Science and Engineering School of Economics and Management Beijing China (GRID:grid.12527.33) (ISNI:***)

This paper investigates the impact of a secondary market, where retailers can buy and sell excess inventories, on the supply chain. We develop a two-period model with a single manufacturer and two retailers. At the beginning of the first period the retailers order and receive products from the manufacturer, but at the beginning of the second period, they can trade surplus products between themselves in the secondary market. We investigate the impact of the correlated dependence of retailers' demand on both the quantity effect and the allocation effect under the secondary market. Lastly, we study potential strategies for the manufacturer to increase sales with the existence of the secondary market.

在零售商延期付款的订购与供应决策模型中,将企业的初始资金作为企业经营决策的约束条件,允许零售商可以向供应商延期支付货款.研究了零售商在不同的初始资金下所做出的运营和延期付款决策以及供应商的延期付款利率设置;研究了允许延期付款对供应商的利润以及供应链总利润的影响.分析结果表明,基于资产的零售商延期付款能够极大地提高供应链的利润,对供应链的协调产生积极的影响,但是如果零售商的资产较少时,过量订购又会增加供应商无法收回应收账款的风险.

Systems Science and Systems Engineering 2002年第3期11卷 296-301页

作者： GAO jian-wei, QIU Wan-huaschool of economics & management, beijing university of Aeronautics and Astronautics, beijing 100083, china school of economics & management Beijing University of Aeronautics and Astronautics Beijing 100083 China

This paper reviews the distortion function approach developed in the actuarial literature for insurance risks. The main aim of this paper is to derive an extensive distortion operator, and to propose a new premium principle based on this extensive distortion operator. Furthermore, the non-robustness of general distortion operator is also discussed. Examples are provided using Bernoulli, Pareto, Lognormal and Gamma distribution assumptions.
